4.2.11 TIM Connectors
TIM connectors provide 4 communication links (Comports) and a Global Bus to the FPGA.
The comports which are available on the SMT348 are CP0, CP1, CP3, and CP4.
They allow interfacing to Sundance TIM modules or to a Host PC providing that you
implement a Comport Interface inside the FPGA. (See 2.1)
The Comport interface is available in Sundance SMT6500 support package.
The FPGA io banks hosting the Comport signals are powered using Vcco = 3.3v.
The TIM connectors also provide power/ground, reset and various control signals.
References and specifications for these connectors are available in
TI TIM specification &

4.2.12 DIP Switches
One four-position DIP switch is connected to the CPLD to provide control over the selection of
the configuration bitstream source and a special reset feature called “TIM Confign”.

The Flash erase & program operations are operated by the CPLD.
Commands are provided via Comport3 from an application running on a Host or DSP.
Status information from the Flash is given over Comport3 as well.
